Make observations of plants and animals to compare the diversity of life in different habitats.
The Idaho Content Standards for Science (2022) outcome 2-LS-2.1 (Life Sciences) for Grade 2 says: “Make observations of plants and animals to compare the diversity of life in different habitats.” This Fieldbook unit teaches it hands-on, with everyday materials and a printable teacher guide and student sheet for every lesson. Official wording: Idaho Content Standards for Science (2022).
Who Lives Here? Grades 3–4 · partly supports this outcome
A schoolyard survey with string squares and hand lenses, sorting animals by their features, life cycles from caterpillar to butterfly, and who can live in which habitat. Students look, count and sketch but never collect or harm. Works in any climate and any country, in a garden, on pavement or in a desert.
- Who lives in our schoolyard? 45–60 min
Teams lay a 1 m square of string in two different spots in the schoolyard and count every kind of living thing they can find, without touching or taking anything. They sort what they find into living, once living and never alive, and compare the two spots.
- Who can live here, and who can't? 45–60 min
Teams compare what lives under a board with what lives on the bare ground beside it, and feel which is damper. Then they judge six animals against the schoolyard's food, water and shelter, and argue with evidence which can live here well, which less well and which not at all.
